description The invention discloses a heat-conductive two-sided flexible copper clad laminate and a manufacturing method thereof. The heat-conductive two-sided flexible copper clad laminate comprises a first copper foil, and a first heat-conductive polyimide layer; a heat-conductive adhesive layer is coated on the first heat-conductive polyimide layer, and a second copper foil is cladded on the heat-conductive adhesive layer; the manufacturing method comprises the following steps: preparing the first copper foil and the second copper foil, preparing a heat-conductive adhesive and heat-conductive polyamide acid; coating the heat-conductive polyamide acid composition on the first copper foil, performing high temperature imidization to obtain the first heat-conductive polyimide layer; coating a layer of the heat-conductive adhesive on the first heat-conductive polyimide layer, drying, pressing together with the second copper foil or a second heat-conductive one-sided flexible copper clad laminate, and curing.
